TecDoc: "Loading data failed – check the configuration file" – How to Fix It

If you see the error "Loading data failed. Check the configuration file" when starting TecDoc, it typically means the application cannot read or access its configuration settings properly. Follow these steps to resolve the issue.

Common causes

• Missing or malformed configuration file (syntax, encoding, wrong keys).
• Incorrect connection settings to the TecDoc database or data files (host, port, credentials).
• Wrong file paths for TecDoc data (XML/CSV/SQL dumps or indexed files).
• Insufficient file or directory permissions.
• Version mismatch between client and TecDoc data set (schema changes).
• Required environment variables not set or incorrect.
• Network issues blocking access to remote TecDoc services or license server.
• Corrupt data files or incomplete data import.
• Software dependency or library missing (e.g., database client, XML parser).

1. Locate the configuration file

The main configuration file is usually:

• Windows: C:\ProgramData\TecDoc\TecDoc.conf or tecdom.ini
• Network installation: \\server\share\TecDoc\config\tecdom.ini

For old versions (pre‑2018):
HKEY_CURRENT_USER\Software\TecDoc\Settings → verify DataPath string value. tecdoc loading data failed check the configuration file
